title: "Convert Polar CIELUV (HCL) to CIELUV"
---

### Description

Convert colors from the polar representation of the CIELUV color space,
also known as HCL (Hue-Chroma-Luminance) color space, into CIELAB
coordinates. Inverse function of [LUV_to_polarLUV](colorspace.colorlib.colorlib.LUV_to_polarLUV.qmd).

### Usage

<pre><code class='language-python'>colorlib.polarLUV_to_LUV(L, C, H)</code></pre>

### Arguments

<dl class="pyp-list param-list">
  <dt style = "white-space: nowrap; font-family: monospace; vertical-align: top">
   <code id="colorspace.colorlib.colorlib.polarLUV_to_LUV:L">L</code><code class="argument-class">numpy.ndarray</code>
  </dt>
 <dd>Values for the polar `L` dimension (Luminance).</dd>
  <dt style = "white-space: nowrap; font-family: monospace; vertical-align: top">
   <code id="colorspace.colorlib.colorlib.polarLUV_to_LUV:C">C</code><code class="argument-class">numpy.ndarray</code>
  </dt>
 <dd>Values for the polar `C` dimension (Chroma).</dd>
  <dt style = "white-space: nowrap; font-family: monospace; vertical-align: top">
   <code id="colorspace.colorlib.colorlib.polarLUV_to_LUV:H">H</code><code class="argument-class">numpy.ndarray</code>
  </dt>
 <dd>Values for the polar `H` dimension (Hue).</dd>
</dl>

### Return

<code>list</code>: Returns corresponding CIELAB chromaticities as a list of
`numpy.ndarray`s of the same length as the inputs (`[L, U, V]`).
